Bent to shut up football supporters' song (8)
I believe the answer is:
penchant
'bent' is the definition.
(I've seen this in another clue)
'shut up football supporters' song' is the wordplay.
I cannot quite understand how this works, but
'song' could be 'chant' (song sung by a crowd) and 'chant' is found within the answer.
'shut up' could be 'pen' (pen can mean to shut in or enclose) and 'pen' is present in the answer.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
'to' is the link.
Can you help me to learn more?
(Other definitions for penchant that I've seen before include "Predilection, preference" , "'Predilection, a strong liking (8)'" , "Partiality" , "Disposition" , "Fondness (for) - bias (towards)" .)
